Locked Screen Application Navigation via Radial Reference Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses, such as smartphones, face challenges in improving manipulability from a locked state to application start-up.
Innovation Solution
An information processing apparatus that includes a detector to identify the interaction position of a manipulation body on a display screen and a controller that, when the screen is locked, arranges display items based on a reference point, the last contact position of a first manipulation, and starts up an application corresponding to a display item in the direction of a second manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking function is implemented to prevent unintended input manipulation, then security and reliability are improved, but manipulability and ease of operation deteriorate
Solution Approach 1:
The system performs preliminary arrangement of display items around the reference point (last contact position) before the user needs to select an application. This allows the user to immediately see and access frequently used applications without needing to unlock the device first, resolving the contradiction by preparing the interface in advance while maintaining the locked state for security.
Solution Approach 2:
The patent introduces an intermediary interface layer between the locked state and full application access. This intermediary layer displays a subset of display items (applications) around the reference point, allowing limited but useful interaction without compromising security. This mediator enables partial functionality while maintaining the protective locked state.
2Ease of operation
If multiple display items are arranged on the locked screen for quick access, then manipulability is improved, but device complexity increases
Solution Approach 1:
Instead of uniformly distributing all display items across the screen, the patent applies local quality by concentrating display items in the peripheral regions around the reference point. This creates a localized area of high accessibility while keeping the center area (reference point) clear and simple. The complexity is localized to specific regions rather than distributed throughout the entire interface.
Solution Approach 2:
The patent transitions from traditional linear or grid-based arrangement to a radial/dimensional arrangement around the reference point. Display items are positioned in peripheral regions at different angular positions around the center, creating a multi-dimensional spatial organization that improves accessibility without significantly increasing perceived complexity.
3Ease of operation
If display items are arranged radially around the reference point, then accessibility and manipulability are improved, but layout complexity increases
Solution Approach 1:
The radial arrangement applies local quality by positioning display items in specific peripheral regions around the reference point rather than uniformly across the screen. Each display item is placed in an optimal location based on its importance and usage frequency, creating localized zones of accessibility that improve operation ease without requiring complex global reorganization of the entire interface.

AI summary
An information processing apparatus includes a detection unit configured to detect a position of a manipulation body on a display screen and a control unit configured to, if a first manipulation on the display screen in a locked state is detected, display, on the display screen, icons to be arranged based on a reference point indicating a position of the manipulation body when the first manipulation is completed, and if a second manipulation indicating a direction from the reference point is detected, start up an application corresponding to the icon specified by the second manipulation. An associated method and computer readable storage medium are also described.
